Yes, a one-cam nock will continue to move down as the string stretches on both sides equally. Of course if twists are taken out on only one side of the string the nock can move up or down depending which side of the string is altered.russ said:Most single cam bows with long strings that anchor to the same cam will have the nock point move down as the string gets longer.
I'm missing it? I should have used "ends" instead of "sides" but other than that I have no clue? I need to go back down in my workshop to find out where I am on this... BRBFS560 said:Paul, please read your first paragraph carefully.
Yes, but when you shorten or lengthen only one end of the string it moves center and changes which way the nock moves. When you only lengthen the nock end of the string the one-cam string behaves much like a two-cam string and moves up.FS560 said:Paul, lengthening the string should be lengthening the string no matter which end of a one cam string you untwist because the idler wheel will roll and the string twist will eventually stabilize while shooting. The idler wheel section will slip on the wheel until the twist in the whole string is stabilized.
I moved the string on the pegs just to make the experiment go faster... The effect should be the same, and because the effect is greater by moving from peg to peg you can really see what is happening.russ said:Paul why don't you try lengthening the string by untwisting it and leaving it on the Same peg rather than moving the pegs? My experience with a 96.5" PSE Carrera strings leads me to believe that a one cam string that stretches causes the nock point to move down not up!
Jim - Ah yes, but the stablization would take so long because of the idler serving it would drive you nuts... The peep would never settle down.FS560 said:Paul, in your original paragraph I referred to, you talked about untwisting the string, not changing pegs.
For changing pegs you are correct, however, for twisting and untwisting as you originally stated, the string will stabilize by slipping on the idler wheel.
By changing posts it is possible to reposition the whole string within the system and the idler will roll to accomodate the new setting. But the twists will not have to stabilize from side to side.
